Occurs after the focused object has been changed in a List Editor's control.
The FocusedObjectChanged event's data class is EventArgs.
Handle this event to process the focused object. To access the object, use the ListEditor.FocusedObject property.
Do not mix a View's focused object changes with property value changes. To track object instance's changes, handle the IObjectSpace.ObjectChanged, INotifyPropertyChanged.PropertyChanged or other suitable events.
